D203B Pyroelectric Infrared Radial Sensor with Cheap Price

All-Purpose Dual Element Pyroelectric Infrared Radial Sensor D203B


The pyroelectric infrared sensor detects infrared radiation on the basis of the characteristics that the polarization of pyroelectric material changes with temperature. Dual compensated sensing elements are applied to suppress the interference resulting from temperature variation. As a result, the operating stability of the sensor is greatly improved Our products can be used in many applications.
